300-415 Question 87
Select 3An enterprise is deploying Cisco SD-WAN controllers in a private data center. During the deployment process, the administrator is required to configure the vManage, vBond, and vSmart controllers. Which of the following requirements must be fulfilled to ensure the deployment is successful?
- A
vManage must be assigned a valid certificate signed by a trusted Certificate Authority (CA).
- B
vBond must have a public IP address or be accessible via NAT.
- C
vSmart should be directly connected to the WAN edge routers for seamless communication.
- D
All controllers must have synchronized system time using an NTP server.
- E
vBond must be deployed within the same subnet as vManage.
Show answer and explanation
Correct answers: A, B, D
Explanation
When installing SD-WAN controllers, certain requirements must be met to ensure proper operation. vManage needs a valid CA-signed certificate for secure communication, vBond must be reachable via a public IP or NAT to facilitate device registration, and synchronized system time using an NTP server is essential for all controllers to avoid operational issues. These requirements are critical for a successful deployment.
- A. Correct.
vManage requires a valid certificate signed by a trusted CA to establish secure communication between SD-WAN components. This is a mandatory requirement.
- B. Correct.
vBond serves as the orchestrator and must be reachable by WAN edge devices via a public IP address or NAT. This ensures proper communication during the initial device registration.
- C. Incorrect.
vSmart does not need to be directly connected to the WAN edge routers. Instead, it communicates with other controllers and edge devices over the SD-WAN fabric.
- D. Correct.
All SD-WAN controllers require synchronized system time using an NTP server to ensure proper operation and avoid certificate validation issues.
- E. Incorrect.
vBond does not need to be deployed in the same subnet as vManage. It can be deployed in a different location as long as it is reachable.
